To display the measurements with specific units, use the meas command.

meas [--metric|--ppb|--nolc]
Table 1. Parameters for meas command
Parameter Value Mandatory Description
(none) No Prints out all measurements with gases in parts per million (ppm) units and with linear correction.
--metric Fixed No Prints out all measurements with gases in metric (µg/m3) units and with linear correction.
--ppb Fixed No Prints out all measurements with gases in parts per billion (ppb) units and with linear correction.
--nolc Fixed No Prints out all measurements, without linear correction and with gases in parts per million (ppm).
